Short Radius 180° Return Bends introduction

When two pipes run parallel to each other and a connection needs to be made between them to allow fluid moving down one pipe to be returned up the other, a return bend is the fitting most commonly used. There are a range of settings in which such fittings can be useful. For example, in a solar hot water heater, a grid of parallel pipes linked to each other with U-bends can be used to maximize exposure to the sun so that water heats as it moves through the array of pipes.
